This indispensable safety switch is a crucial component mandated by global standards for every photovoltaic power system. Complying with IEC 60364-7-712, it ensures that maintenance of the PV converter can be safely conducted. The British standard, articulated in BS7671 - Part 712.537.2.1.1, emphasizes the necessity of providing means to isolate the PV converter from both the DC and AC sides, facilitating secure and efficient maintenance.
The EDS1 series isolation switch is expertly crafted for power systems with DC 1200V or below and rated current of 32A or less. Perfect for infrequent switching operations, it can simultaneously disconnect 1 - 2 MPPT lines. Specially designed for high-voltage DC transmission systems, it's ideal for cutting off high voltage DC current between solar panels and inverters, ensuring safe and efficient power management.
Product Benefits
The isolator switch is crucial for ensuring an electrical circuit is fully de-energized during service or maintenance. Featuring IP66 enclosures and a range of options, it is adaptable for various inverter types. Commonly employed in electrical distribution, it ensures equipment can be safely serviced by cutting off its power source. Essential in electrical substations, it allows for the isolation of apparatus like circuit breakers, transformers, and transmission lines for maintenance. Primarily designed for safety isolation, it is not intended for routine circuit control.
